B.Recreational uses,such as boating and swimming
C.Industrial uses,such as manufacturing
D.Agricultural uses such as watering crops
The main use of freshwater worldwide is the agricultural uses such as watering crops. Thus, the correct option is D.
What is freshwater?Freshwater is the water which contains only minimal quantities of dissolved salts and minerals, thus distinguishing it from that of sea water or brackish water. All the freshwater ultimately comes from precipitation of atmospheric water vapor, reaching the inland lakes, rivers, and groundwater bodies directly, or after the melting of snow or ice.
Healthy freshwater environments are the main water supply for drinking, growing crops, manufacturing, energy, and transport purpose. They also help to prevent erosion, dispose of waste material and provide natural protection against flooding.
Therefore, the correct option is D.

Bacteria are known to change the kinds of fatty acids they produce as the temperature of their environment changes. What types of changes in membrane fatty acids would you expect as the temperature drops? Why?
Answer:
Bacteria has the ability to adapat according to the changes in the temperature. Bacteria has fatty acid cell membrane and can alter its composition to adapt the changes in temperature.
When the temperature drops, changes in the fatty acid membrane of bacteria are as following:
cell membrane become rigid and limit the flow of nutrients or decrease membrane fluidity.High concentrate of unsaturated fatty acids starts producing in order to fulfil the limited acitivity.Optimal temperature is required for the growth of bacteria, that is why bacteria changes cell membrane composition. If the nutrients flow will not be limited then it can affect the internal cells of the bacteria and it will not be able to survive inthe extreme conditions.
Hence, bacteria adapt according to the extreme temperature.
Some animals that try to adapt to climate changes eventually die due to starvation, as climate change alters the

Answer: See image
Explanation:
Cartilage is composed of chondrocytes and chondroblasts, immersed into the extracellular matrix. When the tissue is fixated, lacunae are also visible.
Bone formation involves osteoprogenitor cells, osteoclasts, osteocytes in lacunae, osteoblasts, extracellular matrix, and central ducts.
---------------------------------------------------------
Cartilage and bone are two specialized types of connective tissues.
Cartilage cells are
Chondrocytes → placed in small places of extracellular matrix with collagen fibers.Chondroblasts → are in charge of the extracellular matrix formation.When fixating a piece of tissue, the cells shrink by cytoplasm retraction, leaving a space between the cell and the extracellular matrix. This space is known as lacune or condroplast.
Once the chondroblast secreted the extracellular matrix, they turn less active, becoming Chondrocytes. These cells are bigger-sized and ovoid-shaped. Central chondrocytes arrange in small groups.
Cartilage does not have vessels, so cells nourish through nutrients that diffuse through the matrix.
Cartilage extracellular matrix is composed of fibrous proteins that provide stability -Type II collagen- and deformation resistance -GAGs-. This tissue is rigid but provides flexible support to specific regions. It places in areas where there is constant and direct compression. It is also involved in the endochondral ossification process.
Bone tissue differentiates from other tissues because of the mineralized extracellular matrix. This tissue provides support and protection due to the rigidity and hardness of the matrix. The bone cells are:
OsteocytesOsteoprogenitores → in charge of osteoblasts productionOsteoblasts → Synthesize and secrete osteoid matrix that will later calcifyOsteoclasts → Phagocytic cells in charge of osseous resorption and bone modulation.Among the matrix, there are spaces called lacunae. Each lacuna contains an osteocyte.
Osteoprogenitor cells produce osteoblast cells. When the extracellular matrix mineralizes, some of the osteoblasts get trapped in lacunae and turn into osteocytes. Nexus union canaliculus joint trapped osteoblasts and osteocytes.
In compact tissue, the bony matrix is arranged into concentric superposed laminae, with lacunae and osteocytes can be found in between. These laminae are arranged around a central longitudinal canal. The whole unit -matrix, lacunae, and canal- compose the osteone.

Genetic analysis identified a 10 kb segment of human DNA that correlated to a protein-encoded disease phenotype. How would you use at least three methods to identify the 1 nucleotide in this 10 kb that is responsible for the disease phenotype? Note that there are on average ~8 nucleotide polymorphisms in 10 kb. You do have family members, model organisms, and a biochemical assay available to you.
Explanation:
In the given question, the DNA segment of human can be sequenced or analysed through three processes:
2. DNA sequencing: DNA sequencing is the method by which the sequence of the nucleotides which are adenine, thymine, guanine and cytosine are sequenced in the correct order.
1. DNA probes: probes are synthesised nucleotide sequence which binds to specific sites of DNA. Since these probes are complementary to the specific region therefore the DNA polymorphic sequence can be sequenced.
3. Polymerase chain reaction: PCR is the technique which can amplify or replicate the DNA sequence but this involves the isolation of specific DNA sequence.

5. organ system
Explanation:
Biological organization or levels of organization is defined as the hierarchy of complex biological structures present in the systems that starts with simplest structures and the complexity increase with hierarchy levels.
It organize biological structures from lowest level to the highest level, such as from atom to biosphere.
A functional group of tissues in an organism helps them to perform several activities is called an organ. for example - heart, constitute of several tissues.
A group of cells that functions similarly and have similar structure is called tissue. for example: Epithelial tissue
A living thing that carries out the processes of life is classified as organism. an organism under of the process of reproduction and give birth to other life.
The basic unit of life for all organisms is called a cell. All the organism are made up of different types of cell. for example: Clara cells found in airways of the lungs.
A group of organs that work together to perform specific activities for an organism is classified as an organ system. For example - respiratory system, it constitute of several organs such as lungs (organs), nose, , trachea, pharynx, larynx and bronchi which together performs respiratory function.
Hence, the correct matches of levels of organization that satisfy these definitions are:
1. organ
2. tissue
3. organism

Consider a locus with two alleles, A1 and A2. Mutation happens at this locus, but in a way such that A1 mutates to A2 with probability u and A2 mutates to A1 with probability v. If u = v (and neither of them = 0), the equilibrium frequency of the A1 is expected to be [Hint: set u and v to specific numbers that are equal to see what happens]:
Answer:
The equilibrium frequency of the A1 (p = v/(u+v)) is expected to be equal to the equilibrium frequency of the A2 (q = 1 - p)
Explanation:
Available data:
Locus with two alleles, A1 and A2The probability of A1 mutating to A2 is P(A1->A2)=uThe probability of A2 mutating to A1 is P(A2->A1)=vV=Unor V or U is equal to cerop is the frequency for A1 and q is the frequency of A2.The equilibrium frequency of the A1 is expected to be p = v/(u+v)
The equilibrium frequency of the A2 is expected to be q=1-p=1 - (v/(u+v))
For example, if V = U = 0.005, then
p = 0.005/(0.005+0.005) = 0.005/0.01 = 0.5q = 1-p = 1-0.5 = 0.5The equilibrium frequency of A1 = The equilibrium frequency of A2. The rate of mutation is equal for both alleles.

Select all that apply.
If you wanted to try and identify or classify archaea or eubacteria, you would _____
study their habitat
study their genetic make-up
study their shape and arrangement
conduct Gram staining
study how they gain energy and nutrients
study how they move
Answer: study their habitat
study their genetic make-up
conduct Gram staining
Explanation:
Study their habitat: The members of domain Archea can be identified easily as these organisms are thermophiles and halophiles which means they can be found in extreme heat and extreme saline conditions. Eubacteria are prokaryotic organisms that can be found everywhere on planet Earth.
Study their genetic make-up: Although the members of domain Archea and domain Eubacteria are prokaryotes but they can be identified as separate organisms through their genetic-make up.
Conduct Gram staining: The cell membranes of the Archea do not possess peptidoglycan thus they take up the gram negative stain. The eubacteria may take up gram positive or gram negative stain.
Over abundance of nutrients in the water is most likely to cause harm to which group of organisms?
A. Any organism that uses calcium carbonate to build support or protection.
B. Top tier predators that eat a lot of smaller fish
C. All organisms because it creates giant dead zones where nothing can survive.
D. Human populations through sea level rise
Answer:
Option-C
Explanation:
The flow of nutrients from the sewage and industries is the cause of the nutrient pollution in water bodies. These chemicals get accumulated in the water bodies affecting the aquatic ecosystem to a very large extent.
The increased level of nitrogen and phosphorus causes eutrophication which is also known as algal-boom. These nutrients cause the massive growth of algae which decreases the oxygen level of the water bodies. This increases BOD level of the water bodies which does not allow the growth of other aquatic species.
As a result of this, the dead zones are created where nothing can survive and therefore is the correct answer.
Thus, Option-C is the correct answer.

Explaining Below V
Explanation:
There are 5 different kinds of climates globally.
Tropical
Dry
Temperate
Continental
Polar
Tropical climates are very hot and humid. There's lots of rain (estimated around 59-60 inches per year). The average temperature tends to be over 60°F or 18°C. Plants you can find are incredibly diverse in both plants and animals. You can find animals such as monkeys, parrots, anacondas, jaguars, tigers, and many more. The tropics have the greatest plant diversity on the planet. The climate generally is centered around the equator.
Dry climates are generally very warm and dry. Humidity is very unlikely as everything is mostly dry heat. There's very little precipitation. Dry climates usually consist of deserts (Fe: Sahara desert). Plants such as cacti, succulents, wildflowers, and small trees, shrubs, and grasses. Animals can vary from things such as tarantulas, rattlesnakes, foxes (only some), camels, and rabbits. Depending on the desert, the heat can shoot up past 100°F while being frigid at night.
Temperate climates are generally warm summers with storms and mild winters. Plants can range from owls, raccoons, sparrows, meadowlarks, deer, and occasionally bears. This climate fluctuates the most in temperature compared to other climates. Plants can range from things like clover plants to a common bean.
Continental climates have mediocre summers with very cold winters. In the winter, snowstorms and strong winds are most likely. Sometimes, the temperature can drop below -22°F. Plants can range from Lavender and fern to Carolina Lupine and Silver maples. Animals can consist of squirrels, chipmunks, prairie dogs, skunks, and raccoons.
Polar climates are frigid. Its cold year round. There's animals such as polar bears, foxes, wolves, and caribou. Plants can vary from Tundra moss to Arctic Willow. Plants are generally smaller and are more like tiny shrubs.

Scientists have recently rejected "Protista" as a kingdom because as evolutionary and molecular knowledge continues to increase, the relationships among organisms are strengthened that weren't previously considered. It continues to be found that many protists don't share common ancestry with other protists that don't exclude other groups, such as plants, animals, and fungi. Protists had been previously classified through what they are not: plants, fungi, or animals. They share no characteristics that aren't also shared by "nonprotists."
The three main ways protists can move are through cilia, flagella, and pseudopods. All of these structures help protists to move in different ways through their environment.
The eukaryote that causes red tide is known as a dinoflagellate.
The eukaryotes that push carbon to the bottom of the ocean are known as diatoms. This is important to the ecosystem because it lowers the overall carbon dioxide levels in the air and buries the carbon deep in the sea.
The endosymbiotic theory posits that eukaryotes emerged when one or more prokaryotic cells ingested another prokaryotic cell, leading to the eventual eukaryotic cell.
